Abstract
Description
- This application claims the benefit of U.S. Provisional Application No. 61/476,096 filed on Apr. 15, 2011, the disclosure of which is hereby incorporated by reference in its entirety.
- Delivery vehicles for pressurized fuel and other liquids, such as liquefied petroleum gas (LPG), propane, butane, and so on, typically include a large holding tank located rearwardly of the cab. A fuel sending unit is typically mounted on top of the tank and includes a float that rides on the surface of the liquid. The float is connected to a pivoting float arm which is in turn connected to the lower end of a driven shaft that rotates about its axis in response to float movement. A magnet is typically located at the upper end of the driven shaft for magnetically driving an indicator associated with a gauge head when the shaft rotates, to thereby display a liquid level condition of the tank to an observer.
- As shown in
FIG. 1 , the prior art gauge head 1 is shown mounted on avertical wall 2 of atank 3 associated with a delivery vehicle. The gauge head 1 includes amounting base 5 mounted on thevertical wall 2 of the tank. Anindicator dial 4 extends parallel with thevertical wall 2 of the tank. Abracket 6 extends between themounting base 5 andindicator dial 4 for securing the mounting base and indicator dial together. As shown, theeye 7 of a user is below the level of theindicator dial 4, causing the user to look upwardly towards the indicator dial. Depending on the position of the pointer (not shown) on the face of the dial (not shown), level reading errors can occur because of the parallax effect, i.e. the actual position of the pointer with respect to the dial face is different from the user's point of view, due to the angle at which the user must observe the pointer and dial face. Accordingly, actual liquid level in the tank will be different from the observed liquid level on theindicator dial 4. - It would therefore be desirous to provide a simple, straight forward solution that would reduce or eliminate parallax reading errors while avoiding high development and manufacturing costs associated with redesigning the gauge head, fuel sending unit and/or tank.
- In accordance with one aspect of the invention, a gauge head for indicating liquid level within a container is operatively connectable to a liquid level sending unit. The gauge head includes a mounting base adapted for connection to the container, an indicator dial assembly operatively connectable to the liquid level sending unit for indicating liquid level, and at least one bracket with a rear mounting wall connected to the mounting base and a front mounting wall connected to the indicator dial assembly. The mounting walls are oriented at an acute angle with respect to each other such that the indicator dial assembly extends at the acute angle with respect to the mounting base. In this manner, the indicator dial assembly can more easily be viewed by a user from an angle to thereby reduce parallax reading errors.
- In accordance with a further aspect of the invention, a gauge head for indicating liquid level within a container is operatively connectable to a liquid level sending unit. The gauge head includes: A) a circular mounting base adapted for connection to the container, the mounting base including openings extending along a periphery thereof; B) an indicator dial assembly being operatively connectable to the liquid level sending unit for indicating liquid level, the indicator dial assembly comprising: i) a rear bezel; ii) a dial housing supported by a circular flange formed in the rear bezel; iii) a dial face located within a circular depression of the dial housing, the dial face including indicia for indicating a level of liquid within a container; iv) a pointer mounted for rotation with respect to the dial face, wherein rotation of the pointer is proportional to a level of liquid within the container; v) a driven magnet assembly having a housing with the pointer connected thereto and at least one magnet located in the housing; vi) a needle bearing extending through the driven magnet assembly and fixedly connected to the dial housing for rotation of the driven magnet assembly in response to a level of liquid within the container; vii) a lens positioned over the dial face; viii) an annular gasket surrounding an outer periphery of the lens; and ix) a front bezel with an inner flange that receives the lens and gasket and an outer flange that receives the rear bezel for securing the indicator dial assembly together; and C) first and second brackets, each bracket having: i) a rear mounting wall connected to the mounting base; ii) a front mounting wall connected to the rear bezel of the indicator dial assembly; and iii) a side wall extending therebetween. The mounting walls are oriented at an acute angle with respect to each other such that the indicator dial assembly tilts at the acute angle with respect to the mounting base, whereby the indicator dial assembly can more easily be viewed by a user looking at the pointer and dial face from an angle to thereby reduce parallax reading errors.
- In accordance with yet a further embodiment of the invention, a mounting bracket for orienting an indicator dial at an angle with respect to a mounting base of a gauge head includes a rear mounting plate adapted for connection to the mounting base, a front mounting plate adapted for connection to the indicator dial, and a side wall extending between the rear and front mounting plates. The front and rear mounting plates are oriented at an acute angle with respect to each other such that the indicator dial and mounting base are oriented at the acute angle when connected to the mounting bracket.

The mountinghole 80 is sized to receive a spacer 82 (FIG. 5 ) and one of thefasteners 62 to mount the indicator dial assembly to thebracket 18. Thespacer 82 ensures that there is sufficient clearance between thebracket 18 andrear wall 56 of theindicator dial assembly 14. A nut (not shown) or other threaded device can be located at the rear end of thefastener 62 for securing the components together. - As best shown in
FIGS. 6B and 6C , thefront mounting plate 70 extends at an acute angle A with respect to therear mounting plate 68 such that the front mounting plate converges toward the rear mounting plate in a direction from right to left, as shown inFIG. 6B . In this manner, the indicator dial assembly is mounted at the acute angle A (FIG. 2 ) with respect to the mountingbase 12 so that the dial face can more easily be viewed by theeye 7 of a user when the fuel sender is mounted above eye level on atank 3 or at any other position were parallax reading errors may occur. - With particular reference to
FIGS. 7A to 7C , thebracket 16 is arranged as a right-side bracket and is therefore preferably labeled with the designation “R” (FIG. 7A ). Thebracket 16 is similar in construction to thebracket 18, and is therefore preferably generally U-shaped (FIG. 8C ) and includes a rear mounting wall orplate 88, a front mounting wall orplate 90, and a side wall orplate 92 extending between the rear and front mounting plates. Acentral opening 94 is preferably formed in therear plate 88 andside plate 92 that coincides with one of theopenings 24 on the mounting base 12 (seeFIG. 4 ). Mountingholes 96 are also preferably formed in therear plate 88 on either side of thecentral opening 94 and are sized for receiving fasteners 78 (FIGS. 4 and 5 ) that thread into theapertures 22 for mounting thebracket 16 to the mountingbase 12. Thefront plate 90 is also preferably triangular in shape and includes a mountinghole 98 located proximal to an apex region of thefront plate 90. The mountinghole 98 is sized to receive a spacer 82 (FIG. 5 ) and one of thefasteners 62 to mount the indicator dial assembly to thebracket 16. Thespacer 82 ensures that there is sufficient clearance between thebracket 16 andrear wall 56 of theindicator dial assembly 14. A nut (not shown) or other threaded device can be located at the rear end of thefastener 62 for securing the components together. - As best shown in
FIGS. 7B and 7C , thefront mounting plate 90 extends at an acute angle A with respect to therear mounting plate 88 such that the front mounting plate converges toward the rear mounting plate in a direction from left to right, as shown inFIG. 7B (opposite of theFIG. 6B direction). Preferably the acute angles of thebrackets indicator dial assembly 14 is mounted at the acute angle A with respect to the mountingbase 12 so that the dial face can more easily be viewed by theeye 7 of a user (FIG. 2 ) when the fuel sender is mounted above eye level on thetank 3. However, it will be understood that the angle between the front and rear mounting plates can differ for each bracket where it is desirous for the gauge head to tilt downwardly and to the right or left. - The
brackets - It will be understood that the term “preferably” as used throughout the specification refers to one or more exemplary embodiments of the invention and therefore is not to be interpreted in any limiting sense.
- It will be further understood that the term “connect” and its derivatives refers to two or more parts capable of being attached together either directly or indirectly through one or more intermediate members. In addition, terms of orientation and/or position as may be used throughout the specification denote relative, rather than absolute orientations and/or positions.
- It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof. For example, a single unitary bracket member incorporating the plates and angles of the separate right and left brackets can be provided without departing from the spirit and scope of the present invention. It will be understood, therefore, that this invention is not limited to the particular embodiments disclosed, but is intended to cover modifications within the spirit and scope of the present invention as defined by the appended claims.
